Professor White gives the ruSults Of his cX
prrimrntS furnishing with each, tables when
show the amounts and character oi eftiliZer'
used; the yield per acre; The gain or los
compared with no manure; the loss or gam
due to nitrugrnouS matter; the economiC
results per acre, etc. In this review OF his
rcnnri however. I can only give the Object n
his experiments and the conclus ions arrived
al without entering upon the details OF thf
:cXp"riiuent itself. There is no subject o
deeper interest to our cotton raising Srctlo>
than this Tie best fertilizers TO Dc nSca III u,
raising cotton, when So many are IN inc
mark ct, is II question which comes up To each
farmer every year. lie has not the facilities
for accurat" experimentation that Professor
White has had. and the results OF TINS dis.
tfnguiShcd chemists experiments should he
scanned With care. They furnish conclusions
which IL would take the former many years
to arrive at from his annual experience.
EXPERIMENT NUMBER ONE.
The objects of his first experiment were tc
determines:
lst. Whether the cotton plant derives the
nitrogen necessary for its growth from tile
atmosphere or from the soil.
%. II in whole or In part from the SOIL
which of the following nitrogcnous materials
IL prefers, viz: Nitrate of soda, sulphate o
bone.
Sd. The relative economic Tor money value
of each of the materials nsed.
And his cone luSiOnS reached are:
l. NitrugenOuS manurCS increase the yleld
and the cotton plant therefore requires thitt \
portion OF lis nitrogen nc supplied throush
tho soil. This conclusion has uniformly Deen
reached in each of Il series Of SIX years cH
prrimrntS.
Q. Using quantities Of the difference nitro
gcnous materials to furnish approSimate!y "
the same quantities OF nitrogen, the mate
ria's s:0nd in the followin order OF eYcei,
lenc": Cotton seed meal, raw bone, dried
blood. Suiphate OF ammGnic, nitrate ol SODA.
3. Tie amount of nitrogcnous matter used
Is apparently Il proportion capable Oh Sielu,
ing GOOD results. 1t represents III the mixed
fertilizer about 2I per cent. of ammonia
which may be regarded as II safe average llm'
4. FinanciaIly, all the ni'rogenons matters
paid well for their use. In TINS respect ,iey
rank as follows: Cotton seed meal. dried
blood, raw bone, suiphate OF ammonia, NJ
5. Cotton seed meal may he regarded rs the
best and cheapest heterogeneous ierliliZer lol
cotton.
EXPERIMENT NUMBER TWO.
The object of experiment number two was
to determine:
the relative agricultural and economic
values tn cotton q. dincrcat forms and com.
hiraliona OF phOsphnric acid. rs follows viz:
phosuhntc Of lime, and "insoluhlc" phos'
ihatr of lime in the forms of ta) Charleston

3. Economically considered, soluble phos::
nhatc. reverted phosphate. Crchil Hin and
steamed bone, paid for their use lii the ordCr
named. The uSr of floats was attended WIN

EXPERIMENT NUMBER THREE.
The n!,lrct Of experiment number three was
10 determine:
Thr relative agricultural and economic
valvcs for cotton of the principal, potash
Sa.;S sold In commerce. VIZ: Mnrlhte o: POI
rS'l and kainit, and his conclusion WAS, aGTl'
cultural and economically, kainit IS superior
la luuliatr Of potash as u source OF potash Tor
cotton.
EXPERIMENT NUMBER FOUR.
Tho object of experiment number four was
q test the results Of icrtiiiZinS with CHEAP
rumpuSts compared with equal Quantities Oh
high priced commercial fertilizers, and to
lest Tie relative values OF cotton seed and cot.
ton seed meal in compoSts, aud his conclu-
giunS are:
|. III" mixture containing the cotton seed
meal mndc the highest yield. That contain.
ing cotton seed made the next highest; Both
exceeded the yield from The commercial fer
ti!iZcrS used in competition.
.. Financially, the cotton seed meal mix
tins case all paid very well for their use.
EXPERIMENT NUMBER FIVE.
The object Of experiment 20. was to de
trrrnInc:
10 determine the effect OF non-nitrogenous
organic matter wien mixed with mineral
manure upon corn, compared with the effect
of utroarGuuS organic matter.
Nnd his conclusion is that:
Tho result OF this experiment confirms the
conclusion drawn from similar experiments
previously made that nitrogcnous matter un
lcr corn does not pay.
EXpERTMESr NUMBER SIX.
The object of experiment No. was to dc
1crlnlnr: 49, " .
The relative advantages Of "pulling fodder
from corn and of allowing the blades To re-
uain on the stalk until :hc crop was made
was made this season under conditions near
~ !,lcmii:al with those of IL similar expert
mnnt last season.
And the results were:
